LSAI Channel becomes Bad, Device Failure and Output Voltage Error in DV Diagnostics

Hello experts,

Could someone tell me what could be the reason why suddenly, the LSAI and LSAO channels have Bad, Device Failure (Status: Output Voltage Error)? Though the field values are good, but the status has this error which made the OInteg BAD.

I've checked the voltage in the terminal and they are ok (between 15Vdc - 24Vdc).

Thanks for answering.
